The built-in maximum power point tracking engine (MPPT) can better capture changes in lighting, and it can work even in rainy weather. It can maximize the capture and collection of sunlight. The inverter is compatible with a variety of conventional solar panels with an open circuit voltage of 22~60V, and the panel can exert its best performance through technical means. The power output mode of us Micro-Inverter is reverse transmission technology, which supplies power to the load first, and then uploads the excess power to the local power grid. Its conversion efficiency is as high as 95%. The product has multiple national invention and appearance patents , And has CE, CEC, INMETOR and other regional and national product certification.
